Note: Pearson Correlations are shown in parenthesis below partial correlation in the above table. For above dataset, ribosomal genes are removed and all other factors are considered for partial correlation analysis. Sample size is 73 genes. Significant correlations with fRNA coverage are shown in bold; p-values: # = 0.1, * = 0.05, ** = 0.01, *** = 0.001, **** = 10⁻⁴.
